The square root of 7744 is:

  1. 98
  2. 92
  3. 88
  4. 82
Show answer and solution

Correct answer: C. 88

1. The number ends in 4, so its square root ends in 2 or 8. 2. Since 7744 is between 80² = 6400 and 90² = 8100, the root is in the 80s. 3. Testing 88: 88² = 7744, so the square root is 88. _Source: RRB Group D (RRC) PYQ, held 27-10-2013, Q.85._

If 1120 / √x = 80, then x = ?

  1. 125
  2. 196
  3. 225
  4. 336
Show answer and solution

Correct answer: B. 196

1. Rearrange: √x = 1120 / 80 = 14. 2. Square both sides: x = 14². 3. So x = 196. _Source: RRB Group D CEN-02/2018 PYQ, Q.50._
